Description
本発明は、筐体に対して開閉及び着脱が可能な蓋体を有する電子機器に関する。 The present invention relates to an electronic apparatus having a lid that can be opened and closed and attached to and detached from a housing.
従来、例えば筐体の内部に設けられた電池収納部の開口を塞ぐための電池蓋のように、使用者によって開閉操作が可能な蓋体を有する電子機器がある。筐体に対して開閉可能な蓋体を有する電子機器の中には、通常の開閉操作とは別に特別な操作によって筐体から蓋体を取り外すことが可能な構造の電子機器がある。 2. Description of the Related Art Conventionally, there is an electronic device having a lid that can be opened and closed by a user, such as a battery lid for closing an opening of a battery housing portion provided inside a housing. Among electronic devices having a lid that can be opened and closed with respect to the housing, there is an electronic device having a structure in which the lid can be removed from the housing by a special operation in addition to a normal opening and closing operation.
例えば電池収納部に通常使用の電池よりも大型の外部電源装置を挿入することが可能な電子機器では、電池蓋を開いて外部電源装置を電池収納部に装着した時に外部電源装置の一部が電池収納部から突出する。そのため、電池蓋と外部電源装置とが干渉を起こすといった問題が起こる。この干渉を避けるために、電池収納部に対する外部電源装置の装着時に電池蓋の取り外し操作により電池蓋を筐体から取り外せるような蓋体保持構造を有する電子機器が知られている。 For example, in an electronic device in which a larger external power supply device than a normally used battery can be inserted into the battery compartment, when the battery cover is opened and the external power supply device is attached to the battery compartment, a part of the external power supply device is Projects from the battery compartment. Therefore, there arises a problem that the battery lid and the external power supply device interfere with each other. In order to avoid this interference, there is known an electronic apparatus having a lid holding structure that allows a battery lid to be removed from a casing by an operation of removing the battery lid when an external power supply device is attached to the battery housing.
更に、上記のように筐体から取り外しが可能な蓋体を有する電子機器としては次のものが提案されている(例えば、特許文献1参照)。特許文献1記載の電子機器において、筐体には蓋体が嵌まり込む開口部が設けられており、開口部内壁には少なくとも一対の穴部が形成されている。蓋体の側面には開口部内壁の一対の穴部にそれぞれ係合可能な突起部が形成されている。筐体の開口部内壁の穴部と蓋体の突起部とが係合することで、蓋体が筐体に係止される。 Furthermore, the following is proposed as an electronic apparatus having a lid that can be removed from the housing as described above (see, for example, Patent Document 1). In the electronic device described in Patent Document 1, the housing is provided with an opening into which the lid is fitted, and at least a pair of holes are formed in the inner wall of the opening. Projections that can be respectively engaged with the pair of holes in the inner wall of the opening are formed on the side surface of the lid. The lid is locked to the casing by engaging the hole in the inner wall of the opening of the casing with the protrusion of the lid.
蓋体の一方の突起部は使用者の操作により係合の解除が可能となっている。一方の突起部の係合を解除した状態で、別の穴部と係合状態にある他方の突起部を支点に蓋体を回転させて持ち上げ、蓋体の片側が筐体の開口部から浮いた状態にして、残っていた方の係合箇所の穴部から他方の突起部を抜いて蓋体を取り外す。筐体に蓋体の取り付けを行う時は、取り外し作業の逆を行えばよい。 One projection of the lid can be disengaged by a user operation. With one protrusion released, the lid is rotated by using the other protrusion engaged with another hole as a fulcrum, and one side of the cover is lifted from the opening of the housing In this state, the other protrusion is removed from the hole of the remaining engagement portion, and the lid is removed. When attaching the lid to the housing, the removal work may be reversed.
次に、電子機器の筐体と蓋体との係合部が蓋体の回動による開閉のための回転軸となっている蓋体保持構造について図7を用いて説明する。 Next, a lid holding structure in which an engaging portion between a casing and a lid of an electronic device serves as a rotation shaft for opening and closing by rotation of the lid will be described with reference to FIG.
図7は、従来例に係る電子機器の蓋体と蓋保持部材を示す図であり、(a)は、蓋体と蓋保持部材を示す斜視図、(b)は、蓋体端部が蓋保持部材よりも高くなる位置まで蓋体を持ち上げた状態を示す斜視図である。 7A and 7B are diagrams showing a lid and a lid holding member of an electronic apparatus according to a conventional example, wherein FIG. 7A is a perspective view showing the lid and the lid holding member, and FIG. It is a perspective view which shows the state which lifted the cover body to the position which becomes higher than a holding member.
図7において、蓋体120は、蓋体120の側面に設けられた軸部123a、120aと、電子機器の筐体側の蓋保持部材102に設けられた軸受け部102a、102bとをそれぞれ係合させることで(図7(a))、蓋保持部材102に保持される。前記係合により、蓋体120は電子機器の筐体に取り付けられる。蓋体120の軸部123a、120aは同軸上に配置されている。これにより、蓋体120は、軸部123a、120aを結ぶ線をシャフト(回動軸)として回動可能である。 In FIG. 7, the lid 120 engages shafts 123 a and 120 a provided on the side surface of the lid 120 and bearings 102 a and 102 b provided on the lid holding member 102 on the housing side of the electronic device, respectively. (FIG. 7A), the lid is held by the lid holding member 102. The lid 120 is attached to the casing of the electronic device by the engagement. The shaft parts 123a and 120a of the lid 120 are arranged coaxially. Thereby, the cover body 120 can be rotated using a line connecting the shaft portions 123a and 120a as a shaft (rotating shaft).
蓋体120の軸部123aの動きはシャフト操作部材126の操作と連動しており、シャフト操作部材126を矢印で示す横方向にスライドさせることで(図7(a))、軸部123aを蓋体120の内部に退避させることが可能である。この操作により、軸部123aと軸受け部102aの係合が解除される。更に、軸部123aと軸受け部102aの係合を解除した状態で、軸受け部102bを支点にして蓋体端部が蓋保持部材102よりも高くなる位置まで蓋体120を持ち上げ(図7(b))、軸受け部102bから軸部120aを抜き取る。これにより、蓋体120を蓋保持部材102から取り外すことが可能な構造になっている。 The movement of the shaft portion 123a of the lid body 120 is interlocked with the operation of the shaft operation member 126. By sliding the shaft operation member 126 in the lateral direction indicated by the arrow (FIG. 7A), the shaft portion 123a is covered. It can be retracted inside the body 120. By this operation, the engagement between the shaft portion 123a and the bearing portion 102a is released. Further, in a state where the engagement between the shaft portion 123a and the bearing portion 102a is released, the lid body 120 is lifted to a position where the end portion of the lid body is higher than the lid holding member 102 with the bearing portion 102b as a fulcrum (FIG. 7B). )), The shaft portion 120a is extracted from the bearing portion 102b. As a result, the lid 120 can be detached from the lid holding member 102.
上記従来例で示した電子機器において、蓋体の開き方向の操作性を改善するためには、ロックを解除すると自動的に所定の位置まで蓋体が開放されるように、蓋体が開き方向に付勢されている構成が望ましい。蓋体の開き方向の付勢を行うためには、開き方向の付勢部材を筐体と蓋体に対して付勢状態で当接させる必要がある。 In the electronic device shown in the above conventional example, in order to improve the operability in the opening direction of the lid, the lid is opened in the opening direction so that the lid is automatically opened to a predetermined position when the lock is released. A configuration that is biased to is desirable. In order to bias the lid in the opening direction, it is necessary to bring the biasing member in the opening direction into contact with the housing and the lid in a biased state.
しかしながら、上記従来例で示したような取り外し可能な蓋体を有する電子機器においては、上記のような付勢部材を設けると、筐体に対する蓋体の取付時に付勢部材を付勢しながら取り付ける必要があり、蓋体の取り付け作業が困難になるという問題があった。また、蓋体の取り付け作業を阻害しないように付勢部材の付勢量を制限すると、付勢による蓋体の開き角度を十分に得ることができないという問題があった。 However, in an electronic device having a removable lid as shown in the conventional example, when the biasing member as described above is provided, the biasing member is attached while biasing when the lid is attached to the housing. There was a problem that it was necessary and the attachment work of a cover body became difficult. Further, if the biasing amount of the biasing member is limited so as not to hinder the attachment work of the lid, there is a problem that the opening angle of the lid due to the bias cannot be obtained sufficiently.
本発明の目的は、筐体に対する蓋体の取り付け作業性に優れる電子機器を提供することにある。 The objective of this invention is providing the electronic device which is excellent in the attachment workability | operativity of the cover body with respect to a housing | casing.
上記目的を達成するために、本発明は、一対の軸受け部を有する筐体と、前記筐体の前記一対の軸受け部に対してそれぞれ回動可能に嵌合する一対の軸部を有すると共に、前記一対の軸部のうち少なくとも一方の軸部が軸方向に退避可能に構成され、前記一対の軸部を介して前記筐体に対して開閉可能な蓋体と、前記筐体に当接する当接部を有すると共に、前記蓋体を前記筐体に対して開き方向に付勢する付勢部材と、を備え、前記蓋体の前記一方の軸部の退避に連動して、前記蓋体の前記筐体に対する回動範囲内で、前記付勢部材によって前記蓋体を開き方向に付勢する範囲が小さくなるように、前記当接部を移動させることを特徴とする。 In order to achieve the above object, the present invention includes a housing having a pair of bearing portions, and a pair of shaft portions that are rotatably fitted to the pair of bearing portions of the housing. At least one shaft portion of the pair of shaft portions is configured to be retractable in the axial direction, and a lid body that can be opened and closed with respect to the housing via the pair of shaft portions, and an abutment against the housing. And a biasing member that biases the lid in the opening direction with respect to the casing, and in conjunction with retraction of the one shaft portion of the lid, Within the rotation range with respect to the casing, the contact portion is moved so that a range in which the cover member is urged in the opening direction by the urging member is reduced.

The battery lid unit 20 is configured to be detachable from the device housing 1. Details of the configuration that allows the battery lid unit 20 to be attached and detached will be described later. In addition, what is shown by the code | symbol 25c is the protrusion part of the below-mentioned urging member 25. FIG.
図2は、電池蓋ユニット20の電池蓋カバー24を取り外した状態の内部構成を示す図である。 FIG. 2 is a diagram showing the internal configuration of the battery lid unit 20 with the battery lid cover 24 removed.
図2において、電池蓋ユニット20の蓋ロック爪22は、蓋本体21の水平方向にスライド可能であり、蓋ロック爪付勢部22aによって蓋ロック爪先端が蓋本体21から突出するように付勢されている。蓋ロック爪22には、爪操作部(不図示)が一体に設けられている。蓋ロック爪22の爪操作部をスライド操作することで、蓋ロック爪先端を蓋本体21の内部に退避させることができる。 In FIG. 2, the lid lock claw 22 of the battery lid unit 20 is slidable in the horizontal direction of the lid main body 21, and is urged by the lid lock claw urging portion 22 a so that the end of the lid lock claw protrudes from the lid main body 21. Has been. The lid lock claw 22 is integrally provided with a claw operating portion (not shown). By sliding the claw operation portion of the lid lock claw 22, the end of the lid lock claw can be retracted inside the lid main body 21.
スライドシャフト23には、軸方向に退避可能な可動軸23aと、シャフト操作部23bが一体成型されている。スライドシャフト23のシャフト操作部23bは、スライド操作が可能であり、電池蓋カバー24(図1参照)の開口部から露出するように構成されている。スライドシャフト23のシャフト操作部23bをスライド操作させることで、可動軸23aを軸方向(図2の右向きの退避方向)に移動させることにより可動軸23aを蓋本体21の内部に退避させることができる。 The slide shaft 23 is integrally formed with a movable shaft 23a that can be retracted in the axial direction and a shaft operating portion 23b. The shaft operation portion 23b of the slide shaft 23 can be slid and is configured to be exposed from the opening of the battery lid cover 24 (see FIG. 1). By sliding the shaft operating portion 23b of the slide shaft 23, the movable shaft 23a can be retracted inside the lid main body 21 by moving the movable shaft 23a in the axial direction (the retreating direction facing right in FIG. 2). .
蓋本体21には、固定軸21aが一体に形成されている。蓋本体21の固定軸21aとスライドシャフト23の可動軸23a(一対の軸部)とは、同軸となるように配置されている。蓋本体21の固定軸21aとスライドシャフト23の可動軸23aが、機器筐体1側に設けられた一対の軸受け部に対してそれぞれ回動可能に嵌合することにより、電池蓋ユニット20が機器筐体1に対して回動可能に支持される。 The lid body 21 is integrally formed with a fixed shaft 21a. The fixed shaft 21a of the lid body 21 and the movable shaft 23a (a pair of shaft portions) of the slide shaft 23 are arranged so as to be coaxial. When the fixed shaft 21a of the lid main body 21 and the movable shaft 23a of the slide shaft 23 are rotatably fitted to a pair of bearing portions provided on the device housing 1 side, the battery lid unit 20 is connected to the device. The housing 1 is supported so as to be rotatable.
付勢バネ25(付勢部材)は、圧縮バネと捩じりバネの作用を併せ持つコイル部25dを備えている。付勢バネ25のコイル部25dの一方の端部25a(固定端)は、蓋本体21に当接されている。付勢バネ25のコイル部25dの他方の端部25b(可動側コイル端)は、コイル部25dの圧縮による付勢力をもってスライドシャフト23に当接されている。これにより、付勢バネ25はスライドシャフト23を蓋本体21から突出するように付勢する。 The urging spring 25 (urging member) includes a coil portion 25d having both a compression spring and a torsion spring. One end portion 25 a (fixed end) of the coil portion 25 d of the urging spring 25 is in contact with the lid body 21. The other end portion 25b (movable coil end) of the coil portion 25d of the urging spring 25 is in contact with the slide shaft 23 with an urging force due to compression of the coil portion 25d. Thereby, the biasing spring 25 biases the slide shaft 23 so as to protrude from the lid main body 21.
付勢バネ25の可動側コイル端25bから延伸した部分には、機器筐体1との当接部である突出部25cが形成されている。電池蓋ユニット20が機器筐体1に装着されている状態において、付勢バネ25の突出部25cは、コイル部25dの捩じりによる付勢力をもって機器筐体1側の当接部1a(図1参照)に当接する。これにより、付勢バネ25は電池蓋ユニット20を開き方向に回動するように付勢する。 A protruding portion 25 c that is a contact portion with the device housing 1 is formed at a portion extending from the movable side coil end 25 b of the urging spring 25. In a state in which the battery lid unit 20 is mounted on the device housing 1, the protruding portion 25c of the biasing spring 25 has a contact portion 1a (see FIG. 1). Thereby, the urging spring 25 urges the battery lid unit 20 to rotate in the opening direction.
本実施の形態では、付勢バネ25は、スライドシャフト23の可動軸23aを退避方向とは反対の方向である突出方向へ付勢する部材を兼ねる。また、付勢バネ25は、コイル部25dの圧縮方向の付勢力によりスライドシャフト23の可動軸23aを突出方向へ付勢し、コイル部25dの捩じり方向の付勢力により電池蓋ユニット20を開き方向に回動するように付勢する弾性部材である。 In the present embodiment, the urging spring 25 also serves as a member that urges the movable shaft 23a of the slide shaft 23 in the protruding direction that is the direction opposite to the retracting direction. The urging spring 25 urges the movable shaft 23a of the slide shaft 23 in the protruding direction by the urging force in the compression direction of the coil portion 25d, and the battery lid unit 20 by the urging force in the torsional direction of the coil portion 25d. It is an elastic member that urges to rotate in the opening direction.
図3は、機器筐体1に対する電池蓋ユニット20の取り付け作業時の状態を示す斜視図である。 FIG. 3 is a perspective view showing a state when the battery lid unit 20 is attached to the device housing 1.
図2、図3において、機器筐体1に電池蓋ユニット20を取り付ける際の操作は、電池蓋ユニット20を機器筐体1に対して略垂直になるような角度に開いた状態で、固定軸21aを機器筐体1の一方の軸受け部(不図示)に嵌合させる。更に、シャフト操作部23bをスライド操作したまま保持して可動軸23aを蓋本体21の内部に退避させ、蓋本体21の固定軸21aを支点に可動軸23a側を機器筐体1の他方の軸受け部1bと嵌合する位置まで回動させる。更に、シャフト操作部23bの保持を解除して可動軸23aを突出させて、他方の軸受け部1bに嵌合させる。機器筐体1から電池蓋ユニット20を取り外す際の操作は上記と逆の手順となる。 2 and 3, the operation when attaching the battery lid unit 20 to the device housing 1 is carried out with the battery lid unit 20 opened at an angle that is substantially perpendicular to the device housing 1. 21a is fitted to one bearing portion (not shown) of the device casing 1. Further, the shaft operating portion 23b is held while being slid, and the movable shaft 23a is retracted inside the lid body 21, and the movable shaft 23a side is the other bearing of the device housing 1 with the fixed shaft 21a of the lid body 21 as a fulcrum. Rotate to the position where it fits with the part 1b. Furthermore, the holding | maintenance of the shaft operation part 23b is cancelled | released, the movable shaft 23a is protruded, and it is made to fit in the other bearing part 1b. The operation for removing the battery lid unit 20 from the device housing 1 is the reverse of the above procedure.
次に、電池蓋ユニット20を機器筐体1に取り付ける際のスライドシャフト23の操作に伴う付勢バネ25の動作について図4及び図5を用いて説明する。 Next, the operation of the urging spring 25 accompanying the operation of the slide shaft 23 when the battery lid unit 20 is attached to the device housing 1 will be described with reference to FIGS. 4 and 5.
図4は、スライドシャフト23の可動軸23aが突出している状態の電池蓋ユニット20の構成を示す図であり、(a)は、正面図、(b)は、下面図、(c)は、右側面図である。また、図5は、スライドシャフト23の可動軸23aを退避させた状態の電池蓋ユニット20の構成を示す図であり、(a)は、正面図、(b)は、下面図、(c)は、右側面図である。 4A and 4B are diagrams showing the configuration of the battery lid unit 20 in a state in which the movable shaft 23a of the slide shaft 23 protrudes. FIG. 4A is a front view, FIG. 4B is a bottom view, and FIG. It is a right view. 5 is a diagram showing the configuration of the battery lid unit 20 in a state in which the movable shaft 23a of the slide shaft 23 is retracted, where (a) is a front view, (b) is a bottom view, and (c). These are right side views.
図4、図5において、電池蓋ユニット20の蓋本体21には、付勢バネ25の突出部25cが当接するカム部21bが設けられている。付勢バネ25の突出部25cは、図4(c)、図5(c)において左回り方向に捩じり付勢されることにより、蓋本体21のカム部21bに当接している。スライドシャフト23の可動軸23aが蓋本体21から突出している状態では、付勢バネ25の突出部25cは蓋本体21のカム部21bの位置21cに当接している。付勢バネ25の突出部25cは、図4(c)に示すように電池蓋ユニット20の平面方向と略平行に下方向に突出している。 4 and 5, the lid body 21 of the battery lid unit 20 is provided with a cam portion 21b with which the protruding portion 25c of the urging spring 25 abuts. The protrusion 25c of the urging spring 25 abuts on the cam portion 21b of the lid body 21 by being twisted and urged counterclockwise in FIGS. 4 (c) and 5 (c). In a state where the movable shaft 23 a of the slide shaft 23 protrudes from the lid body 21, the protruding portion 25 c of the biasing spring 25 is in contact with the position 21 c of the cam portion 21 b of the lid body 21. As shown in FIG. 4C, the protruding portion 25c of the urging spring 25 protrudes downward substantially parallel to the planar direction of the battery lid unit 20.
スライドシャフト23のシャフト操作部23bを図4(a)において右方向に操作して可動軸23aを蓋本体21の内部に退避させると、スライドシャフト23のスラスト移動に伴って付勢バネ25の突出部25cも図5(a)に示すように右方向に移動する。付勢バネ25の突出部25cは蓋本体21のカム部21bに当接して移動するため、スライドシャフト23の可動軸23aを蓋本体21の内部に退避させた状態では、付勢バネ25の突出部25cはカム部21bの位置21dに当接している。これにより、図5(c)に示すように付勢バネ25の突出部25cの突出方向が右回転方向に移動する。 When the shaft operating portion 23b of the slide shaft 23 is operated rightward in FIG. 4A to retract the movable shaft 23a inside the lid body 21, the biasing spring 25 protrudes as the slide shaft 23 moves in thrust. The part 25c also moves to the right as shown in FIG. Since the protruding portion 25c of the biasing spring 25 moves in contact with the cam portion 21b of the lid main body 21, the protruding spring 25 protrudes when the movable shaft 23a of the slide shaft 23 is retracted inside the lid main body 21. The part 25c is in contact with the position 21d of the cam part 21b. Thereby, as shown in FIG.5 (c), the protrusion direction of the protrusion part 25c of the urging | biasing spring 25 moves to a right rotation direction.
即ち、電池蓋ユニット20を機器筐体1に取り付ける際に、スライドシャフト23の可動軸23aを蓋本体21の内部に退避させると、退避に連動して、付勢バネ25の突出部25cの位置が変化する。電池蓋ユニット20を機器筐体1に取り付けられるとき、付勢バネ25の突出部25cが図4に示す位置にあるときには、電池蓋ユニット20の機器筐体1に対する開き角度が約120°となる位置まで付勢バネ25による開き方向の付勢力が作用する。したがって、電池蓋ユニット20の回動範囲が約120°に対して、付勢バネ25が電池蓋ユニット20を付勢する回動範囲は約120°となる。 That is, when the battery cover unit 20 is attached to the device housing 1, if the movable shaft 23 a of the slide shaft 23 is retracted inside the cover body 21, the position of the protrusion 25 c of the biasing spring 25 is interlocked with the retract. Changes. When the battery lid unit 20 is attached to the device housing 1, the opening angle of the battery lid unit 20 with respect to the device housing 1 is about 120 ° when the protrusion 25 c of the biasing spring 25 is in the position shown in FIG. 4. The biasing force in the opening direction by the biasing spring 25 acts to the position. Therefore, the rotation range of the battery cover unit 20 is about 120 °, and the rotation range in which the biasing spring 25 urges the battery cover unit 20 is about 120 °.
一方、電池蓋ユニット20を機器筐体1に取り付けられるとき、付勢バネ25の突出部25cが図5に示す位置にあるときには、電池蓋ユニット20の機器筐体1に対する開き角度が約90°となる位置まで付勢バネ25による開き方向の付勢力が作用する。電池蓋ユニット20を機器筐体1に取り付ける際には、電池蓋ユニット20の機器筐体1に対する開き角度が約90°となる位置で電池蓋ユニット20を機器筐体1に取り付ける。したがって、電池蓋ユニット20の回動範囲が約120°に対して、付勢バネ25が電池蓋ユニット20を付勢する回動範囲は約90°となる。 On the other hand, when the battery lid unit 20 is attached to the device housing 1, when the protrusion 25c of the urging spring 25 is in the position shown in FIG. The urging force in the opening direction by the urging spring 25 is applied to the position. When attaching the battery lid unit 20 to the device housing 1, the battery lid unit 20 is attached to the device housing 1 at a position where the opening angle of the battery lid unit 20 with respect to the device housing 1 is about 90 °. Therefore, the rotation range of the battery cover unit 20 is about 120 °, and the rotation range in which the biasing spring 25 urges the battery cover unit 20 is about 90 °.
こうすることで、シャフト操作部23bの操作によって、付勢バネ25の突出部25cがカム部21bをトレースすることで、電池蓋ユニット20回動範囲内で、付勢バネ25によって電池蓋ユニット20を開き方向に付勢する範囲が小さくなる。これによって、電池蓋ユニット20を機器筐体1に取り付ける際には、付勢バネ25をチャージすることなく、もしくはごくわずかにチャージするだけで電池蓋ユニット20を機器筐体1に取り付けることができる。 By doing so, the protruding portion 25c of the biasing spring 25 traces the cam portion 21b by operating the shaft operating portion 23b, so that the battery lid unit 20 is moved by the biasing spring 25 within the rotation range of the battery lid unit 20. The range of biasing in the opening direction becomes smaller. As a result, when the battery lid unit 20 is attached to the device housing 1, the battery lid unit 20 can be attached to the device housing 1 without charging the urging spring 25 or only by slightly charging it. .
図6は、電池蓋ユニット20が開き方向の突き当り位置の近傍まで開いている状態を示す断面図である。 FIG. 6 is a cross-sectional view showing a state in which the battery lid unit 20 is opened to the vicinity of the contact position in the opening direction.
図6において、電池蓋ユニット20が機器筐体1に取り付けられている状態では、電池蓋ユニット20の開き方向の突き当り角度(突き当り位置)の近傍で、付勢バネ25の突出部25cが蓋本体21のカム部21bに突き当たるように設定されている。即ち、電池蓋ユニット20の開き方向の突き当り角度の近傍に達するまでは、付勢バネ25の突出部25cが蓋本体21のカム部21bに突き当たることなく機器筐体1の当接部1aに当接し、突き当り角度の近傍に達するとカム部21bに突き当たる。 In FIG. 6, in a state where the battery lid unit 20 is attached to the device housing 1, the protruding portion 25 c of the urging spring 25 is the lid body in the vicinity of the opening angle (butting position) in the opening direction of the battery lid unit 20. 21 is set so as to abut against the cam portion 21b. That is, the protrusion 25c of the biasing spring 25 does not hit the cam portion 21b of the lid body 21 until it reaches the contact angle 1a of the device casing 1 until it reaches the vicinity of the contact angle in the opening direction of the battery lid unit 20. When it comes into contact and reaches the vicinity of the contact angle, it hits the cam portion 21b.
これにより、電池蓋ユニット20の開き方向の突き当り角度の近傍に達するまで、付勢バネ25による電池蓋ユニット20の開き方向の付勢力が作用できるように構成されている。尚、電池蓋ユニット20の開き方向の突き当り角度(突き当り位置)とは、電池蓋ユニット20を開き方向に最大限まで回動させた際の、電池蓋ユニット20が電池収納部を塞いでいる状態(閉じ状態)からの角度(位置)である。 Thus, the biasing force in the opening direction of the battery lid unit 20 by the biasing spring 25 can be applied until the vicinity of the contact angle in the opening direction of the battery lid unit 20 is reached. The abutment angle (abutment position) in the opening direction of the battery lid unit 20 is a state in which the battery lid unit 20 blocks the battery housing portion when the battery lid unit 20 is rotated to the maximum in the opening direction. The angle (position) from (closed state).
上記構成によれば、機器筐体1に着脱可能な電池蓋ユニット20において、上記で説明したように、電池蓋ユニット20の開き方向の突き当り角度(本実施形態では約120°)の位置まで付勢バネ25による開き方向の付勢力が作用する。このとき、シャフト操作部23bを操作すると、付勢バネ25の突出部25cがカム部21bをトレースすることで、付勢バネ25が付勢力を与える角度範囲が約90°に狭められる。したがって、電池蓋ユニット20の開き角度を90°〜120°の間では付勢バネ25の付勢力が作用しないので、電池蓋ユニット20を機器筐体1から取り外す際にも、取り外しやすくなる。これにより、電池の着脱操作性が良好、かつ、取り付け作業性に優れた着脱可能な電池蓋ユニット20の保持機構を構成することができる。 According to the above configuration, in the battery lid unit 20 that can be attached to and detached from the device housing 1, as described above, the battery lid unit 20 is attached to the position of the contact angle in the opening direction (about 120 ° in the present embodiment). The biasing force in the opening direction by the biasing spring 25 acts. At this time, when the shaft operating portion 23b is operated, the protruding portion 25c of the urging spring 25 traces the cam portion 21b, whereby the angle range in which the urging spring 25 applies the urging force is narrowed to about 90 °. Therefore, since the biasing force of the biasing spring 25 does not act when the opening angle of the battery lid unit 20 is between 90 ° and 120 °, it is easy to remove the battery lid unit 20 when removing it from the device housing 1. Thereby, it is possible to configure a detachable battery lid unit 20 holding mechanism that has good battery attachment / detachment operability and excellent attachment workability.
また、付勢バネ25に一体に突出部25cを形成し、付勢バネ25のコイル部25dの捩じりによる付勢力をもって電池蓋ユニット20を開き方向に回動付勢している。更に、電池蓋ユニット20を構成する蓋本体21に、付勢バネ25の突出部25cを機器筐体1側の当接部1aに非当接状態となる方向へ移動するためのカム部21bを形成している。本構成により、電池蓋ユニット20を開き方向に回動付勢する機構と、付勢バネ25の突出部25cを非当接状態となる方向へ移動する機構を、部品を追加することなく実現できる。これにより、操作性に優れた電池蓋ユニット20の保持機構を小型且つ軽量で安価に構成することができる。 Further, a protruding portion 25c is formed integrally with the urging spring 25, and the battery lid unit 20 is urged to rotate in the opening direction by an urging force generated by torsion of the coil portion 25d of the urging spring 25. Further, a cam portion 21b for moving the protruding portion 25c of the urging spring 25 in a direction in which it does not abut against the abutting portion 1a on the device casing 1 side is provided on the lid main body 21 constituting the battery lid unit 20. Forming. With this configuration, a mechanism that urges the battery lid unit 20 to rotate in the opening direction and a mechanism that moves the protruding portion 25c of the urging spring 25 in a non-contact state can be realized without adding any components. . Thereby, the holding | maintenance mechanism of the battery cover unit 20 excellent in operativity can be comprised small and lightweight and cheaply.
以上詳細に説明したように、本実施の形態によれば、機器筐体に着脱及び開閉が可能に構成されると共に開き方向に付勢される電池蓋ユニットに対し、機器筐体の電池収納部に対する電池の良好な着脱操作が可能な開き位置まで開き方向の付勢力が作用する。これにより、機器筐体に対する電池蓋ユニットの取り付け作業性を向上させることが可能となる。また、電池蓋ユニットを開閉する際の電池蓋ユニットの操作性を向上させることが可能となる。 As described above in detail, according to the present embodiment, the battery housing portion of the device housing is configured to be detachable and openable / closable from the device housing and is biased in the opening direction. The urging force in the opening direction acts to the opening position where the battery can be favorably attached and detached. Thereby, it becomes possible to improve the workability of attaching the battery lid unit to the device housing. In addition, the operability of the battery lid unit when opening and closing the battery lid unit can be improved.
